Hi,
I have added this small patch (attached). Unfortunately I got regressions
some in iso_fortran_env_8.f90
and several in unsigned_NN.f90 tests.
Just retesting w/o my patch and already seeing the iso_fortran_env one again.
I am also not totally sure, that I applied both your patches correctly. But
they applied w/o issues with patch -p0.
Regards,
Andre
